Olimex ESP8266 EVB-BAT

ESP8266-EVB-BAT is an evaluation board for the highly-integrated WIFI SoC ESP8266EX. The board can be powered by our OrangeLi-Po battery and comes with a battery charger. It is recommended for beginners with ESP8266. This board is suitablefor research and development of espressifs ESP8266EX chip.

The moduleis used forhome automation, smart plugs, and lights, mesh networks, industrial wireless control, baby monitors, IP cameras, sensor networks, wearable electronics, etc.

TheESP8266EX is very highly integrated SoC which includes Tensilicas L106 32-bit coreprocessor; SRAM; power management unit; RF front end. ESP8266EX has a number of interfaces I2C, SPI, SDIO and also a number of free GPIO pins.

The chip allows the implementation of a WIFI TCP-IP stack with just a few extra components beside the ESP8266EX. Its a very popular IC that attracted a lot of attention upon its launch.
